Getting Started: Building Applications with RL-ARM
Chapter 4. RL-TCPnet Introduction
One of the key middleware components in the RL-ARM library is the RL-
TCPnet networking suite. RL-TCPnet has been specifically written for small,
ARM-based, embedded microcontrollers, is highly optimized, has a small code
footprint, and gives excellent performance. In this chapter, we will first review
the TCP/IP protocol and then examine each feature of RL-TCPnet. Each of the
exercises accompanying this chapter show minimal examples intended to
demonstrate one aspect of RL-TCPnet. Full examples can be found in the board
examples directory
code size for each of these programs is as follows:
TCP/IP – Key Concepts
TCP/IP is a suite of protocols designed to support local and wide area
networking. In order to build a TCP/IP based application you do not need to
fully understand all the protocols within the TCP/IP stack. However, you do
need to understand the basic concepts in to configure your system correctly.
Network Model
The TCP/IP network model is split into four layers that map on to the ISO seven-
layer model as shown below.
The network access layer consists of:
Demo Example
HTTP Server (without RTX Kernel)
Telnet Server
TFTP Server
SMTP Server
DNS Resolver
the physical connection to the network.
the packetizing of the application data for the underlying network.
the flow control of the data packets over the network.
